Specification of Letters Patent.

Patented May 28,1912.

Application filed December 31, 1910. Serial No. 600366.

To all whom 't may concem:

Be it known that I, JOHN SCHWAB, of the city of Winnipeg, county ofSelkirk, and

Province of Manitoba, Canada, and now residing in the borough ofBrooklyn, in the city, county, and Stateof New York, have inventedcertain new and useful Improvements in Heating-Stoves, of which thefollowing is a specification.

My invention relates to heating stoves of the type in which two stovesare employed in combination, the products of combustion of one stovebeing passed through the other stove and the objects of the inventionare to prevent confiiction between the products of combustion of theprimary and secondary stoves in order that the two stoves may be usedsimultaneously, and it consists essentially of the improved constructionand arrangement of parts hereinafter described in detail in theaccompanying specification and drawings. i i

In the drawings: Figure l is a sectional View of an embodiment of theinvention, Fig. 2 is a section along the line 2 to Fig. 1. Fig. 3 is asection along the line 3 to Fig. 1.

Referring to the drawings I represents the primary stove in the form ofan ordi-' nary cooking stove and A represents the way dependent on thatof the' other.

secondary or heating stove. These terms prmary and secondary areemployed solely for convenience in description and not because thefunction of one stove is in aply T e products of combustion of' theprimary stove are adapted to pass into the combustion chamber of thesecondary stove through the medium of a flue J The secondary stove isprovided with any suitable style of grate B, fire pot C, combustionchamber D and flue E leading from one side of the top of the combustionchamber to the chimney F. An air heating chamber G isprovided around thecombustion chamber communicating at the bottom with a' number ofpassageways 10 around the firepot, said heating chamber having apertures12 near the top controlled by sliding dampers 13. To enable the heat tobe conducted' to other rooms or compartments an air connecting conduit His provided leading from the top of the combustion chamber to one ormore other rooms or compartments. To prevent confiiction between theproducts of combustion of the 'two stoves, a battle plate 14: isprovided leading from near the top of the combuston chamber downwardlytion downwardly.

The openingl in the bottom of the combustion chamber, and through whichthe products of combustion from the fire pot may pass, is located at theside ofthe combustion, chamber renote from that into which the flue Jopens and a second baflle plate 15 is provided at the side of the open-'ing and extending upwardly between the bafile plate 14: and the opening16, being adapted to direct the products of combus- .tion upwardly. Thebottom of the combustion chamber between. the battle plate is andadapted to direct the products of combusi closed so that the lower endof the passagei 'way between the baflle plates is out of communicationwith the fire pot.

It will be seen that the present invention enables both stoves to beused sinultaneously without confliction between the products ofcombustion thereof. This is of great use in cold districts such as thenorthwest of Canada and the advantage gained from the use of the heat ofthe waste gas of the cooking stove is very considerable.

What I claim as my invention is:

. 1. In combination a primary stove, a secondary stove, having acombustion chamber, fire pot and a flue leading to a chimney, an

air-heating chamber around the secondary' stove adapted to discharge airin to the room to be heated, a flue connecting the primary stove withthe combustion chamber of the secondary stove and means adapted todirect the products ofcombustion from each stoveparallel with each otherand thus prevent inte'rference between the products of combustion of thetwo stoves when the fires are burning simultaneously, said meanscomprising overlapping bafiie plates.

2. The combination with a primary stove and a secondary stove having afire p'ot, a combustion chamber above the same, having a bottom 'with anopening therethrough at one side and having asmoke outlet at the top, ofa flue connecting the stoves and opening near the top of the combustionchamber of theSecondary stove at the side remote from the opening intothe fire pot, a baffie ;plate adjacent to the wallthr'ough which theflue opens and adapted to direct the products of combustion downwardlyand a second baflie plate spaced from the first battle plate locatedbetween the first bathe plate and the opening in the bottom of thecombuston chamber communcatng With the fire pot and extendng upwardlyfrom the botton of the combuston chamber.

3. A devoe of the class described comprsng in combnaton a prnary stove,and a secondary stove having a fire pot and combuston chanber above thesame, having a botton With an opening into the fire pot at one slde anda smoke outlet at the top, of an a' heating chanber surrounding both thefire pot and eonbuston chamber and through which air s adapted tocrculate, a fiue connectng the two stoves and opening near the top ofthe combuston chamber of the secondary stove at the side remote from theopening into the fire pot, a bafl'le plate adjacent to the Wall throughwhich the fiue opens and adapted to direct the products of combustondownwardly, and a second bafie plate spaced from the first bafie plate,located between the first baffie plate and the opening in the bottom ofthe combuston chamber communcatng With the fire pot and extendngupwardly from the bottom of the conbuston chamber.

In Wtness Whereof I have hereunto set my hand in the presence of tWowitnesses.

JOHN SCHWAB.
